CATO supplies 3-[4-(7-hydroxyhept-1-ynyl)-1-oxo-isoindolin-2-yl]piperidine-2,6-dione (CAS 2570254-43-0), a certified reference material (molecular formula C20H22N2O4, MW 354.40 g/mol) for analytical method development and quality control.
3-[4-(7-hydroxyhept-1-ynyl)-1-oxo-isoindolin-2-yl]piperidine-2,6-dione (C20H22N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
